Abstract
A multilayer film separable adjacent layers includes adjacent layers formed of compositions of dissimilar primary materials. Optionally, at least one of the layers contains a slip additive to change the release tension between adjacent layers. The multilayer film may include an adhesive layer between layers, with the adhesive layer more adhesion compatible with one of the layers than the other. The multilayer film maybe a relatively inexpensive means to produce labels, films, sheets, containers, etc., requiring protection or isolation of one surface without the additional processes of gluing together individual dissimilar layers. A layer of the multilayer film can undergo a visibly observable change when the at least one layer is released from at least one other layer; this can be used as a security mechanism, a broken seal is visibly evident.
